How long does it take to complete the abortion surgery?

Abortion refers to the termination of pregnancy through artificial means due to unexpected pregnancy, illness, etc., which has certain harm to women's reproductive health. Abortion surgery includes vacuum aspiration and curettage. Vacuum aspiration is suitable for intrauterine pregnancy within 10 weeks of pregnancy, while curettage is suitable for intrauterine pregnancy more than 10 weeks, those who want to terminate the pregnancy without contraindications, and those who suffer from certain serious diseases and are not suitable for re-pregnancy.

Vacuum aspiration uses the principle of negative pressure suction to suck the pregnancy out of the uterine cavity. The whole operation takes about 3 to 5 minutes and can be performed in the hospital outpatient department. It is very simple. However, because the fetus is very large, curettage requires medication to soften the cervix before the operation, and then the fetus and embryo are clamped with an oval forceps. At this time, the fetus is very large and bone formation can easily lead to complications such as heavy bleeding, cervical laceration, and uterine perforation. The operation time is relatively long and may even require hospitalization for surgery.
